Origin & Breeding History: 'Agrihydraelf' was bred and developed by the breeder, Niels Arts, in Aalsmeer, Netherlands. It originated from a cross conducted on May 15, 2007, in De Kwakel, Netherlands, between the female parent designated '200129-03', and the male parent designated '20155-01'. From the resulting progeny, 'Agrihydraelf' was selected on April 25, 2009, in Glandorf, Germany, for its inflorescence colour, vigorous plant growth, and suitability for use in "blue staining". 'Agrihydraelf' was first asexually propagated by cuttings on April 20, 2010, in Glandorf, Germany.
Tests & Trials: The detailed description of 'Agrihydraelf' is based on the UPOV report of Technical Examination, application number 2009/2616, purchased from the Community Plant Variety Office, in Angers, France. The trial was conducted by the Groupe d'Étude et de contrôle des Variétés Et des Semences, in Brion, France, from 2011 to 2012. The colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
